[orca-list] OT: Making screencasts with both computer audio and microphone?

[Nolan Darilek <nolan thewordnerd info>]

Wondering if anyone out there has done something like this? I'd like to 
make a screencast where I capture both computer audio and my voice from 
a mic. Essentially, I want my full computer audio stream mixed with my 
mic input and alongside video of my screen. I don't want a recording of 
my computer audio through the external mic, since I want to capture full 
stereo.


I thought about using pulseaudio to do some sort of monitoring setup, 
which would send my audio back through the speakers and thus mix it into 
the output. I can probably avoid feedback with headphones, but then I'd 
hear my own voice, likely with a slight delay, and that might make 
speaking more difficult. Or maybe there's some very advanced magic that 
would mix the streams, mute the audio before it reaches my headphones, 
but still capture it in whatever app I'm using to do the recording? My 
head spins with the possibilities.


Anyhow, wondering if anyone has done this? I've done some research, but 
short of using something like OBS, which I don't even know is 
accessible, I'm not sure what my available options are. I'm not looking 
to stream professionally--I just want something to capture full computer 
audio alongside video, and to mix it with my voice. I also don't know 
that recording both separately will work since syncing later would 
probably be a challenge non-visually.


Thanks.
